Abstract
The invention provides a melt tank for leading glass fiber in the production of a long glass fiber reinforced modified plastic material. The melt tank is formed by jointing a left plate, a right plate, a bottom plate, a top plate, a front plate and a rear plate, wherein the inner wall of the left plate is respectively in transitional joint with the inner wall of the bottom plate and the inner wall of the top plate by rounded corners, and the inner wall of the right plate is respectively in transitional joint with the inner wall of the bottom plate and the inner wall of the top plate by rounded corners; a glass fiber inlet is also arranged on the left plate, and correspondingly, a glass fiber outlet is arranged on the right plate; and electric heating rods are respectively arranged on the left plate and the right plate. The left plate and the right plate of the melt tank are designed into inner rounded angles according to the flow direction of melts in the tank so that the flowing line of the melts in the tank tends to being smooth, therefore, all melts participate in flow cycle and are in a dynamic balance state, and the color appearance and the performance of the product are improved.
Description
Technical field
The present invention relates to the production equipment of long glass fibres reinforced plastic material, relate in particular to a kind of roving glass fiber and strengthen the melt tank that is used to soak molten glass fibre in the modified plastic material production.
Background technology
The key point that roving glass fiber strengthens the modified plastic material production technology is: glass fibre is by a closed mould that fills plastic melt, and the synchronous melt extrusion of extruder draws pelletizing then to mould.Because relate to the performance, quality (deployment conditions of glass in plastics) of product and the operability of producing, the temperature that generally can control the interior plastic melt of mould is higher, the good fluidity of melt like this is to improve the glass dispersiveness.
Summary of the invention
The objective of the invention is to overcome the deficiency that prior art exists, provide a kind of roving glass fiber to strengthen the melt tank that is used to soak molten glass fibre in the modified plastic material production.
Purpose of the present invention is achieved through the following technical solutions:
Roving glass fiber strengthens the melt tank that is used to soak molten glass in the modified plastic material production, constitute by left plate, right panel, base plate, top board, header board and back plate linking, characteristics are: the inwall of described left plate is respectively with the inwall of fillet and base plate and the inwall transition and linkage of top board, and the inwall of described right panel is respectively with the inwall of fillet and base plate and the inwall transition and linkage of top board; Also be provided with the glass import on the described left plate, accordingly, described right panel is provided with the glass outlet; On described left plate and the right panel electrically heated rod is installed all.
Further, above-mentioned roving glass fiber strengthens the melt tank that is used to soak molten glass in the modified plastic material production, and wherein, the material of described left plate, right panel, base plate, top board, header board and back plate is a mould steel.
Substantive distinguishing features and obvious improvement that technical solution of the present invention is outstanding are mainly reflected in:
The present invention designs uniqueness, the left and right sides plate of groove is designed to filleted corner, make the streamline of melt flows in the groove smooth-out, and then make all melts participate in flow circuit, melt is in dynamic balance state, guarantee that time that molten plastic stops equates and short as far as possible in mould, avoid the overlong time that in mould, stops and pyrolysis takes place, thereby improved the color outward appearance and the performance of product.

The specific embodiment
As shown in Figure 1, roving glass fiber strengthens the melt tank that is used to soak molten glass fibre in the modified plastic material production, constitute by left plate 1, right panel 5, base plate 3, top board 4, header board and back plate linking, the material of left side plate 1, right panel 5, base plate 3, top board 4, header board and back plate is a mould steel, the inwall of left side plate 1 is respectively with the inwall of fillet and base plate 3 and the inwall transition and linkage of top board 4, and the inwall of right panel 5 is respectively with the inwall of fillet and base plate 3 and the inwall transition and linkage of top board 4; Also be provided with the glass import on the plate 1 of a left side, accordingly, right panel 5 is provided with the glass outlet; On left side plate 1 and the right panel 5 electrically heated rod 2 is installed all, heats, guarantee temperature in the groove by electrically heated rod 2.In the production, glass is involved along involving direction B, and melt-flow is level and smooth to A in the groove.
The flow direction according to melt in the groove in the production technology, the left and right sides plate of groove is designed to filleted corner, makes the streamline of melt flows in the groove smooth-out, and then makes all melts participate in flow circuit, make plastic melt be in dynamic balance state, improved the color outward appearance and the performance of product.
In the flow process, extrude with mould mouth mould through extruder and extrude, and is in dynamic balance state by plastics in mould for plastic melt.The time that molten plastic stops in mould equates and is short as far as possible, avoid the overlong time that in mould, stops and pyrolysis takes place, influence product color (product colour jaundice) and performance (the aging decomposition), phenomenons such as the melt of having eliminated place, dead angle in the mould is difficult for flowing, overstand.
It is emphasized that: above only is preferred embodiment of the present invention, be not that the present invention is done any pro forma restriction, every foundation technical spirit of the present invention all still belongs in the scope of technical solution of the present invention any simple modification, equivalent variations and modification that above embodiment did.
